We analyze three-dimensional (3-D) deformations of soft body armor in the form of a clamped rectangular plate impacted at normal incidence by a projectile. Results have been computed by the finite elem...

Joint Design for Advance Ceramic Armor under Ballistic Impact

The objective of this research is to develop a new methodology with software tools for the joint design of an advanced composite armor (ACA) under ballistic impact and other loading conditions. An innovative design methodology, topology optimization, is extended for the composite armor joint design problem. This includes ballistic impact analyses of the ACA, function analyses and targets settin...

the effect of task cognitive complexity and time limit on the performance of the learners with different proficiency levels in second language writing skill

this study investigated the effects of manipulating the cognitive complexity of tasks along +/- few elements and the time limits on l2 learners writing performance. to conduct the study, 60 iranian efl learners with two levels of proficiency, low and high intermediate, were selected and assigned to three groups based on the time devoted to task completion. the participants performed both a simp...

Laminated and Hybrid Soft Armor Systems for Ballistic

assessment of the park- ang damage index for performance levels of rc moment resisting frames

چکیده هدف اصلی از طراحی لرزه ای تامین ایمنی جانی در هنگام وقوع زلزله و تعمیر پذیر بودن سازه خسارت دیده، پس از وقوع زلزله است. تجربه زلزله های اخیر نشان داده است که ساختمان های طراحی شده با آیین نامه های مبتنی بر نیرو از نظر محدود نمودن خسارت وارده بر سازه دقت لازم را ندارند. این امر سبب پیدایش نسل جدید آیین نامه های مبتنی بر عملکرد شده است. در این آیین نامه ها بر اساس تغییرشکل های غیرارتجاعی ...

Ballistic Body Armor

P O L Y M E R S Our goal is to prevent the catastrophic failure of ballistic body armor by developing measurements and predictive models to test and determine the long-term reliability of polymers used in ballistic resistant armor. Our approach, which utilizes conventional analytical techniques in addition to newly developed minimally invasive test methods, seeks to identify the chemical and me...
